Chemical solutions, such as hand sanitizer, antibacterial soap and bleach, are believed to clean up and kill the bacteria Escherichia coli and the fungus Aspergillus Niger, this theory was the focus of the experiment. The purpose of this lab was to find out what chemical solution best cleans E. coli and fungus. Samples of both of these organisms were placed on agar Petri dishes, solutions of three cleaners were applied to the dishes and they were then incubated at 37ºC, in an attempt to discover the best cleaning substance to fight off these bacteria and fungus. The data collected was inconclusive for which cleaner works beat to kill bacteria and fungus, but it did show that agar needs to have moisture or else it splits from dehydration; and that hand sanitizer can react to agar and form crystals.
